AI agents invoke safe_swap_calldata to trigger processes or run actions in AIGEN — Open Bounty Protocol for AI Agents. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
safe_swap_calldata can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access safe_swap_calldata gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Build calldata for SafeRouter.safeSwap() — ready to sign and send. Returns the exact calldata + target + gas estimate. The agent retains custody of the private key: we never see it. Workflow: 1. Call this to get { to, data, gas_estimate, preflight } 2. ERC20.approve(saferouter, amount_in) on tokenIn 3. eth_sendTransaction with { to, data, gas, value: 0 } The contract reverts if tokenOut score < 40, emitting SwapBlocked + ScamPrevented. Args: token_in: ERC-20 you're swapping FROM (0x...) token_out: ERC-20 you're swapping TO (0x...) amount_in: Amount in token_in's smallest unit (wei). For 1 USDC use "1000000". amount_out_min: Minimum acceptable output (wei). Use "0" for no slippage protection. stable: True for Aerodrome stable pools (e.g. USDC/USDbC), False for volatile (default). deadline: Unix timestamp; 0 = +30 min from now. chain: Currently only base.. It is categorised as a Execute tool in the AIGEN — Open Bounty Protocol for AI Agents MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the AIGEN — Open Bounty Protocol for AI Agents MCP server in PolicyLayer and add a rule for safe_swap_calldata: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AIGEN — Open Bounty Protocol for AI Agents. Nothing to install.
safe_swap_calldata is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the safe_swap_calldata rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for safe_swap_calldata. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
safe_swap_calldata is provided by the AIGEN — Open Bounty Protocol for AI Agents MCP server (https://cryptogenesis.duckdns.org/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
